"HERE" - Being the USA - That is 100% a Kalinka question.
The factory I'm taliking to is REALLY a Military supplier (amongst other thigs they make MIG parts!). They used before to supply Kalinka and a Finnish gunsmith. Lowish sales.
They have reorganised SERIOUSLY And I hear that shipments are being made to "official" purchasers in "poorer" countries. The term "Banana Republics" was used.
Prior PPO stuff was not bad - but seriously out of date. The other PPO stuff on kalinkas site (looking like this)
are FIXED IMAGE (i.e reticle not centred) and the illumination - I wont say more. I had a 6-24*60 like the PPO4-16 and its currently on a 1000yard gun in the UK. All the same it needed redesign - and has been.
I'm waiting to see how the 8-32*60 is in real life.
But just to set you wondering too
